# TVM in Intel SGX Example
## Setup
This application demonstrates the use of a simple TVM model in the [Intel SGX](https://software.intel.com/en-us/blogs/2013/09/26/protecting-application-secrets-with-intel-sgx) trusted computing environment.
## Prerequisites
1. The TVM premade Docker image
or
1. A GNU/Linux environment
2. TVM compiled with LLVM and SGX; and the `tvm` Python module
3. The [Linux SGX SDK](https://github.com/intel/linux-sgx) [link to pre-built libraries](https://01.org/intel-software-guard-extensions/downloads)
4. [Rust](https://rustup.sh)
5. The [rust-sgx-sdk](https://github.com/baidu/rust-sgx-sdk)
6. [xargo](https://github.com/japaric/xargo)
Check out the `/tvm/install/ubuntu_install_sgx.sh` for the commands to get these dependencies.
## Running the example
If using Docker, start by running
```
git clone --recursive https://github.com/apache/incubator-tvm.git tvm
docker run --rm -it -v $(pwd)/tvm:/mnt tvmai/ci-cpu /bin/bash
```
then, in the container
```
cd /mnt
mkdir build && cd build
cmake .. -DUSE_LLVM=ON -DUSE_SGX=/opt/sgxsdk -DRUST_SGX_SDK=/opt/rust-sgx-sdk
make -j4
cd ..
pip install -e python -e topi/python
cd apps/sgx
```
Once TVM is build and installed, just
`./run_example.sh`
If everything goes well, you should see a lot of build messages and below them
the text `It works!`.
## High-level overview
First of all, it helps to think of an SGX enclave as a library that can be called
to perform trusted computation.
In this library, one can use other libraries like TVM.
Building this example performs the following steps:
1. Creates a simple TVM module that computes `x + 1` and save it as a system library.
2. Builds a TVM runtime that links the module and allows running it using the TVM Python runtime.
3. Packages the bundle into an SGX enclave
4. Runs the enclave using the usual TVM Python `module` API
For more information on building, please refer to the `Makefile`.
For more information on the TVM module, please refer to `../howto_deploy`.
For more in formation on SGX enclaves, please refer to the [SGX Enclave Demo](https://github.com/intel/linux-sgx/tree/master/SampleCode/SampleEnclave/)
1. [Install the Fortanix Enclave Development Platform](https://edp.fortanix.com/docs/installation/guide/)
2. `rustup component add llvm-tools-preview` to get `llvm-ar` and `llvm-objcopy`
3. `pip install numpy decorator psutil`
4. `cargo run` to start the enclave TCP server
5. Send a 28x28 "image" to the enclave model server using `head -c $((28*28*4)) /dev/urandom | nc 127.0.0.1 4242 | python read_results.py`
